Freaky Friday is a children's novel by Mary Rodgers first published in the USA in 1972, in which a teenage girl, Annabelle Andrews, and her mother, Ellen Andrews, switch bodies and learn to understand each other better.
The film Freaky Friday included a soundtrack which featured songs by various artists. The album was called a "mixed bag" by allmusic http://www.allmusic.com/cg/amg.dll?p=amg&sql=10:iwpzefuk3gf2~T1, which specifically cited American Hi-Fi "The Art of Losing," The Donnas' "Backstage", Andrew W.K.'s "She Is Beautiful," and Joey Ramone's "What a Wonderful World" as good, and strongly criticizes the rest of the album.
Freaky Friday is 2003 teen comedy starring Lindsay Lohan and Jamie Lee Curtis as a daughter and mother whose bodies are switched because of an enchanted Chinese fortune cookie. It is a remake of the 1970s original which starred Jodie Foster. It is based on a novel by Mary Rodgers.
